The role of new inflammatory markers in determining disease activation and severity in patients with hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease. Recently published studies have suggested the use of markers of inflammation to monitor HS patients. These studies discuss the platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), pan-immune-inflammation value (PIV), and systemic immune-inflammation index (SIII), which are also used in other inflammatory diseases. This study aimed to compare the blood parameters, including NLR, PLR, SIII, and PIV, in HS patients and healthy individuals, and determine their correlation with disease severity. The study included 81 HS patients and 61 healthy volunteers. The patients' medical records and laboratory values of the control group were reviewed retrospectively. HS severity was assessed using Hurley staging. NLR, PLR, SIII, and PIV values were calculated based on complete blood counts. NLR, SIII, and PIV values were significantly higher in HS patients compared to the healthy control group and were positively associated with disease severity. There was no significant difference observed in PLR values concerning disease severity. This study suggests that NLR, SIII, and PIV values can be utilized as simple and cost-effective tests to monitor disease activity and severity in HS patients. However, larger and more comprehensive studies are needed to establish diagnostic cutoff values, and further evaluation of sensitivity and specificity is required.

The impact of COVID-19 pandemic on psoriasis patients, and their immunosuppressive treatment: a cross-sectional multicenter study from Turkey.

BACKGROUND: Immunosuppressive therapy has been a great concern during the pandemic. This study aimed to evaluate the pandemic's impact on psoriasis patients treated with immunosuppressive drugs. MATERIAL AND METHODS: The multicenter study was conducted in 14 tertiary dermatology centers. Demographic data, treatment status, disease course, and cases of COVID-19 were evaluated in patients with psoriasis using the immunosuppressive treatment. RESULTS: Of 1827 patients included, the drug adherence rate was 68.2%. Those receiving anti-interleukin (anti-IL) drugs were more likely to continue treatment than patients receiving conventional drugs (OR = 1.50, 95% CI, 1.181-1.895, p = .001). Disease worsening rate was 24.2% and drug dose reduction increased this rate 3.26 and drug withdrawal 8.71 times. Receiving anti-TNF or anti-IL drugs was associated with less disease worsening compared to conventional drugs (p = .038, p = .032; respectively). Drug withdrawal causes were 'unable to come' (39.6%), 'COVID concern' (25.3%), and 'physician's and patient's co-decision' (17.4%). Four patients had COVID-19 infection with mild symptoms. The incidence was 0.0022% while it was 0.0025% in the general population. CONCLUSION: Our study shows that psoriasis patients using systemic immunosuppressive do not have a higher, but even lower COVID-19 risk than the general population, and treatment compliance with biological drugs is higher.

The relationship between the severity of coronary artery disease and skin measurement parameters.

PURPOSE: This study aimed to investigate the relationship between skin parameters and CAD. MATERIALS AND METHODS: The study included 50 patients diagnosed with coronary artery disease as the patient group and 45 volunteers without any known coronary artery disease as the control group. The participants' skin TEWL, pH, temperature, electrical capacitance, sebum, and elasticity values were measured using noninvasive methods at the forehead, back, and forearm. FINDINGS: Skin temperature was significantly higher in the back and forehead regions in the patient group. No difference was found between the sebum values of the patient and control groups at the back and forehead. A significantly higher result was obtained for the forearm area. The pH was significantly lower in the patients' forearm, although the obtained values were within the normal range. The TEWL was significantly higher in patients in all three regions. In terms of flexibility, R2 was significantly higher in the back and forehead regions of the patient group, and the R6 was significantly higher in the patient group in all three regions. In addition, there was no correlation between skin parameter and SYNTAX score increase measurements. CONCLUSION: It can be suggested that skin sebum and TEWL measurements can be accepted as cheap and noninvasive methods of predicting CAD.

Coronavirus Disease 2019 (COVID-19) Accompanied by Maculopapular Rash: A Case Study.

A new type of coronavirus (coronavirus disease 2019; COVID-19), which emerged in the People's Republic of China, spread all over the world over time and became a pandemic. Dermatological symptoms seen during the course of the disease have gained importance over time. Studies have shown that many dermatological findings such as erythematous rash, urticaria, pseudo-chilblain, maculopapular, livedo/necrosis, and vesicular lesions may accompany the disease. In this study, a 24-year-old female patient with maculopapular lesions who had no previous history of allergy or dermatological disease and regressed without any dermatological treatment is presented.
